Really!? For all intensive purposes cards stopped after the US entered WW2, roughly after Pearl Harbor (sorry moe berg fans). That’s when paper rationing started, men’s pro baseball went on haitus, and cards production died off (unfortunately as playball was starting to get it right with their 1941 release).
Baseball and it’s cards were primarily US culture (sans the odd ball Cuban and Ruth tobacco issues) back then, so I follow US history in determining prewar.
